There are three main types of bulbs: compact bulbs (CFLs), light-
LEDs (LEDs)
And incandescent lamps.
Here are the pros and cons of each method and ultimately the best value.
Since Thomas Edison invented these traditional bulbs in 1879, they have not changed much.

Pros: \"It depends on how much light you will keep.
If the lights need to be on all the time, CFL is probably the most economical option, \"said Guo Chunlei, associate professor at the Institute of Optics at the University of Rochester.
\"However, if you use it only occasionally every day, incandescent lamps may not be a bad option, as it can take a long time to offset the initial cost of CFL.
They are notorious power changers.
Kelly Cunningham, director of outreach at the California Lighting Technology Center, said that about 90% of the energy used by incandescent lamps is used for light, and only 10% is used for light.
The compact fluorescent bulb looks like a long twisted tube compressed into the shape of a normal bulb. Cost: Your 50-
Cent incandescent lamp can be used 13-
According to the EPA, the price of the watt CFL is about $3, and the duration is about 10 times.
Advantages: these bulbs use 75% less energy than incandescent lamps.
In addition, some state utilities offer rewards to individuals and businesses turning to CFLs, sometimes several dollars per bulb.
Disadvantages: Price is the main obstacle.
Also, the color of light produced by certain types of CFLs may make the mirror look unflattering, which can be a mistake.

The upfront cost of LED lighting systems can be as high as thousands of dollars.
However, like computers and iPhones, LED bulbs may become cheaper over time, which may make them more convincing lighting options.
William Greenhoe, president of PiSAT, said: \"The cost of bright LEDs has dropped by 95% in the past 10 years, by 30% in the past three years, a company that produces solar LED lanterns and flashlights.
Advantages: each LED bulb using direct and powerful LED technology can last 50,000 hours.
For 25 years, five and a half hours a day.
In addition, LED bulbs are not as hot as incandescent lamps, which may make them safer and more efficient in commercial use, especially if they are on 24 hours a day, seven days a week: says Cunningham, if you live in a very cold climate, it may not be a good idea to convert your home lighting system to all LEDs, citing reports that due to the low heat output of led bulbs, canadian consumers end up having greater demand for their home heating systems.
Although some companies guarantee the life of the bulbs, many LED bulbs can only guarantee one year or several years.
\"LEDs have just been on the market, so there is not much regulation or information right now to say if they will fulfill their 50,000-hour commitment,\" Cunningham said . \".
Cunningham suggests that before you decide to upgrade, it boils down to spending, \"see where the energy in your home is going to flow . \".
The kitchen lights are the most commonly used lights in the home, followed by the porch lights, says Cunningham.
Larry Lak, a spokesman for the American Lighting Association, said he used several types of lighting equipment at home, including CFL and incandescent lamps, so he could \"save energy and create the right atmosphere \".
